IMPROVEMENT m LOCQMOTIVE WHEEL-s.

l The Schedule refexred'to in these Letters Patent and making part of the same.

' Be it known that I,- J 01m R, RICHARDSON, of Max Meadows, in the county of Wythe and State of Virginia,haveinvented a new and improved Device. for Preventing Locomotive Wheels from Slipping on Railways; and I do hereby declare that the followiug'is a full, clear, and exact description of the same, reference being had to the accompanying drawing forming a part of thisspecification, in which the figure is a side elevation.

This invention consists'inthe combination with the driving-wheel of a locomotive of an outside row of pi voted spurs, projecting beyond the periphery of. the

wheel, and engaging with the teeth of auxiliary rails, which are laid down outside the main rails, thus ren; dering it impossible for the wheels to slip on the track,

the said spurs being combined with spring arms, which pressagainst themwith force sufficient to keep the spurs up to their work, and yet .not too great to prevent them fromyielding before an immovable obstacle,.so 'as to avoid shocks; and with pins, which hold, the spurs in .their proper position against the pressure of'the springs.

In the drawing--.

A isoueof the locomotive wheels. a, the track on whichit runs.

' b, the projecting spurs, arranged in an annular row .ontthe outside of the wheel.

0, the pins, against which the spurs bear. d, the springs which press the spurs'against the pins R c, the teeth of the auxiliary outside rail.

By this arrangement any slipping of the wheels is rendcred'impossible, exeptjn the veryslightdegrec due to the yieldingnes s of the spurs,'-\vhich yieldinguess is a quality of the spins necessary to guard against fracture.
